the cable "down" button works fine but will only move the cable "up" as well. In other words press up or down button and cable only goes up. So now the cable weight is jammed against the end of the boom. This is 1993 vintage 1000 lb capacity "Tender Lift"... looks like a typical modern dinghy davit. (come to think of it, you can see it in my avatar photo of the boat)
Last time I used it, 6 months ago, worked fine. I'm guessing there is a solenoid valve in there somewhere that is not shifting when the "down" button is pressed but the hydraulic motor comes on regardless and is pressurizing the "up" side of the cable system. Is that it ?
If so, any emergency fixes anyone can think of just to get dingy back on the flybridge for a trip ?
If it matters, this one has power cable only...boom angle and rotation are done manually.
Oh and naturally the two hydraulic fitting positions don't match the drawings in the manual so I have no clue which one is cable up and which is cable down. I figure if I loosen the "cable down" one I might could at least yank the cable down by hand ( while creating a total mess of spilled hydraulic fluid onto rags I place first )
=================
Besides the two hydraulic fittings there is what I presume to be an electromagnet that probably should be shifting a valve....my theory is either that magnet has gone kaput or the valve is just stuck ? It looks good in there....clean, no corrosion...just not used often enough i guess.
=================
As an aside, what an extreme annoyance this would be if it happened in an emergency situation. At least I'm at a dock now.
